Answer:
8.75 hours
Explanation:
What I do is form it into ratio form
224 : 4
490 : n
n is the hour we're trying to find
Since 490 isn't one of the multiples of 224, you divide 224 by itself, giving you 1
You then multiply 490 by 1 to get it
You divide and add again but with the hour (4)
4/224 = 0.0178... x 490 = 8.75 hours
There's how to get your answer
